For years, liberals have claimed that the minimum wage needs to increase to $15 an hour to provide a living wage for full-time workers. The stated goal, as socialist Sen. Bernie Sanders writes on his website, is straightforward, “We must ensure that no full-time worker lives in poverty.”

In one way, the campaign has been remarkably successful. California and New York are phasing in a statewide $15 an hour minimum wage. Numerous cities, including Seattle, Minneapolis and Washington D.C., have passed $15 an hour minimum wage laws as well.

But as sure as the sun comes up in the morning, progressives are now demanding more.

“$15 an hour: A higher wage, but hardly a living,” a CBS News headline from October reads. After bemoaning the inadequacy of the $7.25 an hour federal minimum wage, the CBS story asserts that “even at $15 an hour, life doesn’t get a whole lot easier.”

The main reason for this is the price of housing in many large cities. Restrictive housing policies combined with strong demand have led to extremely high rental prices in places such as New York City and San Francisco. Rather than address the regulations and land use and zoning policies that exacerbate this problem, liberals have found a new solution.

“The arrival of a $15 hourly minimum wage cannot be considered the end of something,” New York Times columnist Ginia Bellafante wrote last week. Her suggestion? A $33 an hour minimum wage for the Big Apple.

Ah, the wonders of progressive economics. Just pass a law mandating that everybody must make at least $68,000 a year — with full medical benefits, vacation time and family leave allowances, of course. But why stop there? Why with a stroke of the pen, we could all be millionaires!
